PAPER-BOARD BARREL AND METHOD or initiative saivin.

Application an August 22, 1922. Serial Nd. 583,552.

To (ZZZ whom it may concern.

Be it known that we, MERRILL WATSON and Hammer J. SMITH, citizens of the United States and residents, respectively, of East Orange, in the'county of Essex and State of New Jersey, and New H-aven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Paper-Board Barrels and Methods of Making Same; and Wedo hereby declare the following to bea full, clear, and exact description of the invention, su ch as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to barrels formed of paperboard or like material and the method of making the same, and comprises certain improvements upon the barrel dis-- closed in application Serial No. 523,306.

The barrel of the aforesaid application is made up of a series of paperboard stavcs which are formed with transversely arranged bends adjacent their opposite ends providing shoulders at the inner side of the staves for the support of the barrel heads and grooves at the outer side of the staves to receive a fastening hoop for holding the parts together, the hoop being arranged just below the plane of the heads. With such construction and arrangement, however, the parts are not as closely and firmly united as it is desirable to have them for some uses to which the barrels are put,

and for such reason it has been one of they main objects of our present invention to improve the constructlon of paperboard barrels of the type in question in a manner.

whereby a tighter and stronger barrel will be produced thanheretofore and one presenting a neat and attractive finished appeaian ce. V V

Other objects and advantages ofthe'invention will be referred to in the detailed description which follows.

Referring now to the accompanying drawings illustrating the invention,I I

Figure 1 is a perspectiveview of a suitable paperboard blank for forming a stave; Fig. 2 is a plan view of a completestave looking towardthe inside;

Fig. 3 is a plan view of the stave from the outside;

Fig. 9 is a, view ofthesame from 611 661)- perspective view of a complete of the posite or under side; and,

Fig. 10 is a acumen the line 10:16 of Fig 8. y

In these drawings, 1 indicates the paperboard blank for foriniiig a single stave,"tl1e. same preferably comprising a. series of plies of rectangular sheet's of paperboard, united by a suitable adhesive,such, for e ample; as silicate of soda, which WilIh'ave the effect of first softening the blank to render the same moreor less plastic and pliable, and subsequentlyto set or harden and retain the blank in the ultimate form imparted there'toby the succeeding operations.

lVhile the blank is still plastic-.or 'soft, due to the action of the adhesive, it is placed in. a. suitable press which reduces the blank to its final stave-like forn1,,"ntt1necomprising a relatively narrow is hallow middle portion outwardly flaring deepening end; sections .3 iwhichhave the'efi. a of the stave it m the 'mid cllegporti dniLtowards the ends. In addition to t ese groove-s2, there are also] formed during the pressing operation transverse bends Y -jacent the respective ends of the isftave,

which bends provide grooves 4: atti e inner 55 at the outer side of the state, the said grooves 4 forming seats to receive and support the barrel heads 6. After removal from the press, the staves are then preferably beveled at their longitudinal edges to assure a close joint between the same at such point.

In making up a barrel from these staves, the required number of staves are assembled in barrel formation and the heads 6 seated in the grooves 4, after which metallic fastening hoops, 7 and 8, are drawn about the staves under sufiicient tension to bring the several parts of the barrel into close contact at their adjacent edges and then, while still under tension, each are fastened together at their ends.

Any desired number of these fastening hoops may be employed according to the size of the barrels or the uses to which they are to be put, but in any event the end hoops 7 will be placed in a position directly opposite the grooves l in which the barrel heads are seated, as shown in Fig. 6, in order to positively lock the heads in said grooves by preventing any outward movement of the staves at such point. As a means to hold the end fastening hoops in their locking position opposite the head retaining grooves 4t, said hoops are bent transversely to conform to the ribs 5, as shown, whereby they will be positively locked against displacement in a direction lengthwise of the barrel.

The ends of the several hoops may be secured together in any suitable way. In the present instance, the ends of the hoop are brought to a position overlapping each other and then locked together by a so-called sealing device, which comprises a plate 10 formed to embrace the lateral edges of the overlapping hoop ends and having cut-outs 11, providing oppositely-located end walls 12, 12, between which bent sections 13 of the overlapping hoops extend for engagement therewith, the engagement of the hoop sec tions 13 with the end walls l2, 12, of the sealing device serving topositively lock the ends of the hoops together. I

r The operation of securing the ends of the hoops by the sealing device in the manner shown and described, that is, drawing the ends of the hoops together under tension and'the'n securing them while under tension by bending or deflecting the sections 13- of the overlapping hoop ends downwardly between the oppositely-located end walls 12, 12, of the plate 10, maybe effected by any suitable means, but is preferably accomplished by a tool especially, adapted for the work but forming no part of our present invention. In order that this sealing operation may be effected in a manner to assure the tension of the hoops being maintained following said operation, the latter preferably takes place opposite one of the I longitudinal grooves or depressions 2 which.

' groove receives the underside of the sealing devlces so that the hoops may he close to the face of the barrel throughout their length.

By sealing the fastening hoops in the manner described, the barrel or container is thereby sealed and cannot have its contents removed or tampered with without destruction of the entire acka 'e as the 1100 s cannot be removed whole without destroying the seals and these cannot be replaced without the special tool required.

What we claim is:

l. A barrel comprising a plurality of ad joining staves, each formed from a blank of paperboard and having a depression in its outer wall and a transverse bend adjacent each end, each of said bends providing a groove at the inner side of the barrel and a raised rib at the outer side thereof, heads seated in said grooves in .the adjoining staves, metallic fastening hoops surrounding the barrel to maintain the staves and heads in fixed relation, said hoops overlying the ribs in position opposite the heads, and fastening devices securing the end-s of the hoops located in position opposite one or more of the said depressions in the staves.

2. A barrel comprising a plurality of ad joining staves, each formed from ablank of paperboard and having a longitudinal groove in its outer wall and a transverse bend adjacent each end, each of said bends providing a groove at the inner side of the barrel and a raised rib at the outer side thereof, heads seated in said grooves in the adjoining staves, metallic fastening hoops surrounding the barrel to maintain the staves and heads in fixed relation, said hoops overlying the ribs and conforming in cross section thereto whereby they will be held in position opposite the heads and against displacement lengthwise of the barrel, and fastening devices securing the ends of the hoops located in position opposite one or more of the said longitudinal grooves in the staves.

ing the staves together by drawing hoops about the same and applying fastening devices to the ends of the hoops atpositions opposite said depressions in the staves While the hoops are held under tension.

5. The method of "forming barrels of staves of paperboard or like material having longitudinal grooves in their outer Walls, which comprises assembling the staves in 1 barrel formation, placing heads in position,

and securing the staves together by drawing hoops about the same and applying fastening devices to the ends of the hoops at positions opposite said grooves in the staves While the hoops are held under tension.

In testimony whereof We afiix our signature.
